Multiquip 15066H1001 Oil Pump Gasket

The Multiquip 15066H1001 Oil Pump Gasket is a genuine OEM sealing component designed for C30HDNI and C30HDN series Mayco concrete pumps, including C30HDNI Precision and C30HDNI Zenith configurations. As a factory-sourced part, it meets the exact material and dimensional specifications of the original, ensuring a proper, leak-free seal at the oil pump interface. Sourced directly through Multiquip's OEM supply chain, this gasket is the correct replacement choice when servicing the oil pump on these concrete pump models. Verify your model code against the fitment list before ordering to confirm compatibility.

Key Features

• OEM Sealing Material: — Manufactured to the original material grade and compression specification, ensuring the gasket seats and seals correctly under operating pressures — not an approximation of the original.
• Direct-Fit Installation: — Matches the original bolt pattern and profile at the oil pump mounting surface, allowing straightforward installation without trimming or reworking.
• Broad C30HD Series Coverage: — Fits C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith concrete pump models, covering multiple engine and configuration variants within the Mayco C30HD family.
• Leak Prevention at a Critical Point: — A failed or compressed oil pump gasket allows oil to escape the pump circuit, leading to lubrication loss and accelerated wear on pump internals — replacing it promptly protects the broader hydraulic and drive system.
• Genuine OEM Traceability: — Part number 15066H1001 is the manufacturer-assigned OEM reference, ensuring you receive the correct component without substitution or cross-reference guesswork.

The oil pump gasket forms a pressure-tight seal between the oil pump body and its mating surface, preventing hydraulic fluid or lubricating oil from leaking out of the pump circuit during operation. In a concrete pump like the C30HDN series, maintaining this seal is essential — oil loss at the pump can starve downstream components of lubrication, causing heat buildup and premature wear. When a gasket deteriorates, hardens, or becomes compressed over time, visible seeping or dripping around the oil pump is typically the first sign that replacement is needed.
